From 140e807dd7d6aa68e601f50a10abd5351e06126f Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Fri, 16 Feb 2007 15:59:06 +0100 Subject: macb: Remove inappropriate spinlocks around mii calls Remove spin_lock_irqsave() around mii_ethtool_gset, mii_ethtool_sset and generic_mii_ioctl. These are unnecessary and harmful because the mii calls may call back into the mdio functions, which may sleep. Pointed out by David Brownell.
